FIRE-EXTINGUISHER AND CHEMICAL ENGINE.

SPECIFICATION forming part of Letters Patent No. 242,675, dated June "7,11881. Application filed February 14,1881. (Model.)

T o all whom it may concern:

BeitknownthatLJAMESBRADNERMOORE, a citizen ofthe United States, residingat New Orleans, in the parishot' Orleans and State of Louisiana, haveinvented certain new and useful Improvements in Fire-Extinguishers, ofwhich the following is a specification.

This invention relates to that class of apparatus for extinguishingtires in which a portable or stationary vessel contains a chemicalsolution and an acid,the latter being contained in a suitablereceptacle, and the union of the chemicals accomplished by fracturingthe acidreceptacle to permit the acid to mingle and combine with thechemical solution in the vessel, the reaction ofthe chemicals by suchunion evolvingcarbonic-acid or other gas, which forcibly ejects theliquid from the vessel upon the fire to be extinguished.

The objects of lny invention are to provide an effective and simplearram ement oi' mechauism for fracturing the acid-receptacle, and toliberate the acid at a point-remote fromthe mouth of theacid-receptacle, and within the chemical solution at a point near theupper portion of the extinguisher-vessel, whereby the union ofthechemicals can be instantaneously effected with ease and convenience.These objects I accomplish by the mechanism illustrated in theaccompanying drawings, in whichl j Figure l is a vertical centralsectional view of the invention applied to an ordinary portablere-extingnisher; Fig. 2, a vertical sectional view on the line x of Fig.l. Fig. 3 represents a detached perspective view of my improved devicesfor supporting the acid-receptacle; and for fracturing the same whenrequired.

The letter A indicates a screw-threaded ring orhead, which is adapted tothe screw-threaded mouth B of the vessel C, and is furnished withhandles D, by which to rotate it for connecting and disconnecting thesame? The ring or head is swiveled on a circular hub, a, of thestationary plate b, and is conned in place by a nut, c. Y

To the under side of the stationary plate b is attached a stirrup,consisting of two parallel bars or frames,`E E, connected at their lowerends by an open ring, F, which constitutes the support for theacid-receptacle. The bars or frames E E are slotted vertically, as at G,the slots extending from end to end of the same, and serving to receiveand guide the ends ot' a cross-head, H, through the center of whichpasses the threaded end of a stem, I, the latter extending through theplate b and ring or head A, and having at its outer end a suitablehandle, J, by which the screw can be manipulated to rotate thescrew-stem and slide the cross-head vertically.

'Io the ends of the crosshead are attached vertical rods K K, which restwithin and are guided in their sliding movements by the slots G of thestirrup, and project beyond the lower end thereof, the lower extendedportions of the rod being connected by a bar, L, which is provided atirs center with an angular pointed projection or lug, M, which isadapted to rise through the opening in the ring F, and constitutes afracturing device which is adapted to advance toward the bottom of theacid-receptacle for breaking or rupturin g the same, as hereinafterexplained.

At a point below the cross-head El the bars or frames E are connected by'a rigid. and station ary crossbar,N, provided on its under side with adepending hub, O, having at its lower edge a projecting ange, d, and onthis hub is arranged a sleeve, P, having an inward-projectin g flange,e, to retain it in place. A spiral or other sprin g, f, is arrangedwithin the sleeve, above its liange e, this spring acting on thecross-bar N and iange of the sleeve to throw the latter downward, suchconstruction permitting the sleeve to yield upward to admit the mouth ofthe acid-receptacle within.

In operation the acid-receptacle R is placed with its bottom resting onthe ring-support F, and the sleeve P is pressed upward to permit themouth of the receptacle to pass under it, after which the sleeve iscaused to press down over the mouth of the bottle by means of the springf, thereby securely confining the receptacle in place. When it isdesired to fracture the acid-receptacle to permit the union of thechemicals the stem I is rotated to elevate the cross-head H, which drawsup the rods Kand the projection or lug M, causing the point ot' thelatter to impinge against the central portion of the bottom ofthereceptacle and force IOO the latter upward until the limit ot'elasticity ofthe bottle is reached, when the receptacle will beeffectively fractured, the point of departure of the fracture alwayscommencing at the bottom of the receptacle. This provides for theliberation of the acid at a point remote from the mouth ot' theacid-receptacle, and within thel chemical solution at a point near theupper portion ot' the vessel, thereby effecting the instantaneous unionand thorough mingling and combination of the chemicals and the promptevolution of the gas.

Although I have shown and described the fracturingdevice as carried andguided against the bottom of the acid-receptacle by means of rodsarranged to move in'vertical slots in the stirrup, I do not wish toconne myself to such arrangement, as the parts could be interchan ged.For instance, the support for the receptacle could be suspended by asingle rod or rods, and the rod or rods carrying the fracturing devicebe arranged at the sides of the saine.

The acid-receptacle is of glass or other suitable material Which can befractured by the action ot' the fracturing device.

l. In a chemical tire-extinguisher, the combination, with a stationarysupport for the acid-receptacle suspended from the top portion of theextinguisher-vessel, of a movable fracturing device arranged beneath thelower end of the said receptacle and connected with devices controllablefrom the exterior of the extinguisher-vessel, for imparting an upwarddrawing action to the fracturing device to break the bottom of theacid-receptacle and liberate the acid at a point near the upper portionof the extinguisher-vessel, substantially as described.

2. The combination, with a stationary support for an acid-receptacle, ofvertically-sliding rods provided at their lower ends with an attachedi'racturing device arranged beneath the said support and connected attheir upper ends with devices controllable from the eXterior 4ot theextinguisher-vessel, for imparting an upward sliding movement to therods, substantially as described.

3. Tile combination, with a support for the acid-receptacle, ot'guidedvertical rods, acrosshead connected with the upper ends thereof, ascrew-threaded stem for. sliding the crosshead, and a fractnring deviceconnected with the lower ends ot' said lrods and adapted to advancetoward the bottom of the acid receptacles by the action of thescrew-threaded stem, substantially as described.

4. The combination, With a support for the acid-receptacle, ot' twosliding rods connected by a cross-head which is moved by a screwthreadedstem, and provided at their lower ends with a bar, to which is lixed anangular projection adapted to advance toward the bottom ot' theacid-receptacle by the action of 65 the screw-threaded stem,substantially as described.
